Product Description
DZD-8 Multi Parameter Water Tester DC Resistivity Meter
The DZD-8 is a cutting-edge geophysical survey instrument designed for groundwater detection projects. This innovative device combines traditional electrical methods with natural electrical techniques, delivering unparalleled performance and precision in field applications.
Advanced Technology
Equipped with an advanced embedded Linux operating system and efficient FPGA technology, our direct current meter ensures real-time data processing with high-precision, high-speed oversampling recording capabilities. This ensures every measurement is captured with utmost accuracy for effective geophysical surveys.
Working Principle
The full-waveform DC electrical conductivity instrument operates based on DC conductivity technology. It detects differences in conductivity between strata by supplying stable current underground and observing the distribution pattern of earth's current field. This enables determination of rock properties (water-poor/water-rich areas) and geological structures (faults, fracture zones).
